只为博褒姒一笑
[zhĭ wéi bó bāo sì yī xiào]
Literally means 'Just for the smile of Bao Si', from a Chinese ancient anecdote where a king arranged for all kinds of entertainments only for the fleeting smile of his concubine, Bao Si. Using this name hints a willingness or act dedicated to making someone important happy, even if at high cost.
